The Presto Pure Automatic Soy Milk Machine is the highest capacity machine of its kind. The Presto Pure is capable of making 1.9 liters of milk at a time. That's just over a half gallon! In thirty short minutes, you'll have fresh, homemade milk with no additives like you'd find in store-bought milk. You can also easily make nut, seed, rice, coconut, hemp, oat milk and more.
